Frozen Blueberry Chocolate Nut Clusters

June is Alzheimer’s and Brain Health Awareness Month , and I’m excited to partner with the U.S Highbush Blueberry Council to create this perfect summer recipe. Plus, I’ll be sharing more information on blueberries and brain health.
I always have a carton of blueberries in my fridge or a bag in my freezer because they’re so versatile, nutritious, and not to mention, easy to reach for and snack on! Both fresh and frozen blueberries contain beneficial vitamins and minerals.

What’s cool about these no bake blueberry nut clusters is that they satisfy your cravings for something sweet, salty, and crunchy all in one! Easy to make and the perfect thing to reach for when you’re trying to beat the summer heat.

Blueberry Nutrition

One serving, or a cup of blueberries contributes essential nutrients including vitamin C, vitamin K, manganese, and phytonutrients called polyphenols.

Good source of vitamin C: Vitamin C is an antioxidant that helps the immune system work properly and helps protect cells from damage caused by free radicals.

Good source of dietary fiber: Blueberries contain 3.6 grams of fiber per serving. Fiber aids in digestion and makes you feel fuller faster. Most of us are not getting enough fiber, so adding more blueberries to you diet in fun ways is an easy way to boost your fiber intake, too.

Blueberries & Brain Health

June is Alzheimer’s and Brain Health Awareness Month and while it’s great to eat blueberries year-round for their health benefits, this month is the perfect time to emphasize adding them to your breakfast, snacks, and meals in a variety of different ways.

We continue to learn so much about the health benefits of blueberries, and a growing body of scientific evidence is currently examining how blueberries can be a part of eating patterns to support brain health, especially as part of an overall healthy lifestyle.1-4

I know, we as millennials, don’t often think about our brain health, but it is important to think about it not only in terms of setting a solid foundation for our own health, but the health of our older relatives, friends, and parents. Diseases like Alzheimer’s and dementia are common in adults 65 and older and the risk increases with age. Sharing a blueberry treat with those older and wiser than us or simply encouraging them to add blueberries to their grocery list is a no brainer, and something I plan to do with my parents!

This treat packs double the goodness with the help of blueberries and walnuts.

Ingredients for Frozen Blueberry Chocolate Nut Clusters

  • Fresh blueberries both fresh and frozen blueberries contain beneficial vitamins and minerals.
  • Walnuts – research suggests that walnut consumption may be associated with cognitive function. And, substantial research supports the inclusion of walnuts in healthy eating patterns that support cardiovascular health. In fact, supportive but not conclusive research shows that eating 1.5 ounces per day of walnuts, as part of a low saturated fat and low cholesterol diet and not resulting in increased caloric intake, may reduce the risk of coronary heart disease.

  • Cashews
  • Dark chocolate / milk chocolate / white chocolate chipschoose dairy-free chocolate to keep this recipe dairy free, if desired.

How to Make Blueberry Nut Freezer Clusters

Making no-bake blueberry nut clusters is super easy. Simply combine fresh blueberries with your nuts of choice in a bowl and gently mix together until combined. I suggest walnuts, almonds and cashews but you can use whichever you have on hand.

Line a plate that will fit into your freezer with parchment paper and scoop a cluster of a few blueberries and a couple of nuts on to the parchment paper. Smoosh it together so that everything is touching or slightly on top of each other.

Melt the chocolate of your choice in a microwave safe bowl. I recommend melting in increments of 20 seconds, mixing after each time. Use a fork to drizzle the chocolate on top of the blueberry nut cluster making sure to cover each berry and nut so that everything sticks together.

While the chocolate is still melted on top of the cluster, sprinkle shredded coconut flakes and add a couple of pumpkin seeds, along with a pinch of salt. Place clusters in the freezer for at least two hours or overnight to harden

When you’re ready to enjoy, simply pull a cluster out of the freezer and eat! Store clusters in a covered container or bag in the freezer for up to three months.

Easy Ways to Add a Boost of Blue to your Day

  • Add blueberries to your breakfast: Think smoothies, oatmeal, pancakes or on top of toast.
  • Snack on a handful of blueberries: Make your own trail mix with dried blueberries, nuts and chocolate chips
  • Bake with blueberries: Whip up a batch of pumpkin blueberry muffins to share with a friend.

  • ½ cup dark milk or white chocolate chips
  • ¼ cup unsweetened shredded coconut

  • In a medium-sized bowl combine blueberries, almonds, walnuts, and cashews. Gently mix together to combine and scoop out about a 2 tbsp. sized cluster of berries and nuts on the parchment paper. Make sure each blueberry and nut is touching the other so that the cluster stays together once frozen.

  • Use a fork to drizzle the melted chocolate over the entire cluster and sprinkle with shredded coconut flakes, pumpkin seeds, and a pinch of salt.
